[0066] The door 100 may include a rear glass 160 and a fixing frame 150 for securing the rear glass 160. The rear glass 160 may be housed within the fixing frame 150. Furthermore, the rear glass 160 may be configured to seal the first chamber 30.

[0067] Door 100 may include a rear panel 140. The rear panel 140 may be mounted on the rear of door 100 to form part of the rear surface of door 100. The rear panel 140 may cover components included in door 100 so that the rear appearance of door 100 is neat.

[0068] Door 100 may include a plurality of locking devices 120. The plurality of locking devices 120 may be disposed on door 100 so that door 100 is secured to and released from body 10. The plurality of locking devices 120 may be housed within rear panel 140. In the drawings, multiple locking devices 120 are provided, but this disclosure is not limited thereto, and door 100 may include a single locking device 120.

[0069] The door 100 may include a housing 200 forming the front surface, upper surface, lower surface, side surface and part of the rear surface of the door.

[0070] The housing 200 may include a front panel 210 forming the front surface of the door 100. The front panel 210 may be formed from a single panel. The edges of the front panel 210 are bent so that the housing 200 can be formed into an approximate box shape with an open portion. The front panel 210 may be bent to form the lower surface of the door 100.

[0071] The housing 200 may include a plurality of flanges 300 connected to the front panel 210. The flanges 300 may include an upper flange 310, side flanges 320, a support flange 330, and a first rear flange 361 and a second rear flange 362, which will be described below. The front panel 210 and the plurality of flanges 300 may be integrally formed with each other. The housing 200 may be formed from a single sheet metal.

[0072] The housing 200 may include a pair of side flanges 320, which form the side surfaces of the door 100 by bending at the side portions of the front panel 210. The side flanges 320 may have a flat panel shape perpendicular to the upper flange 310. The side flanges 320 may be formed by bending at both ends of the front panel 210 in an inward direction toward the door 100. The inward direction may be toward the cavity 30 of the oven 1.

[0073] The housing 200 may include a first rear flange 361, which is formed by bending from the side flange 320 to be parallel to the front panel 210 to form part of the rear surface of the door 100. The first rear flange 361 may be formed by bending from one end of the side flange 320 toward the central portion of the door 100.

[0074] The housing 200 may include an upper flange 310, which is formed by bending at the upper portion of the front panel 210 to form the upper surface of the door 100. The upper flange 310 may be formed by bending from the top of the front panel 210 in the inward direction of the door 100.

[0075] The housing 200 may include a second rear flange 362, which is formed parallel to the front panel 210 to form part of the rear surface of the door 100 by bending downward at one end of the upper flange 310. Specifically, the second rear flange 362 may be formed by bending at the rear end of the upper flange 310. The length of the second rear flange 362 in the direction perpendicular to the side flange 320 may be less than the length of the upper flange 310 in the same direction. Accordingly, the rear surface 310a and the rear end edge 310b of the upper flange 310 may be located on each lateral side of the second rear flange 362. The rear end edge 310b may correspond to an edge formed by the rear surface 310a and the lower surface 310c of the upper flange 310.

[0076] The housing 200 may include a first support flange 331 formed by bending at the upper end of a side flange 320. The first support flange 331 may include a pair of first support flanges 331 formed by bending at the upper end of a pair of side flanges 320, respectively.

[0077] The first support flange 331 may contact and support the upper flange 310. The first support flange 331 may include a first support portion 341 configured to contact the upper flange 310 and a first curved portion 351 configured to connect the first support portion 341 to the side flange 320.

[0078] The first support portion 341 may have a flat panel shape parallel to the upper flange 310. The first support portion 341 may include a first support surface 341a configured to contact the lower surface 310c of the upper flange 310. Specifically, the first support surface 341a may have a planar shape and may correspond to the upper surface of the first support portion 341.

[0079] The first curved portion 351 may have the shape of a curved plate having one end connected to the side flange 320 and the other end connected to the first support portion 341. The first curved portion 351 may include a first curved surface 351a having a curved shape. The first curved surface 351a may have a constant or varying curvature. The first curved surface 351a may correspond to the outer surface of the first curved portion 351 and may be connected to the first support surface 341a.

[0080] Since the first curved surface 351a and the first support surface 341a are connected to each other, a boundary H can be formed, and the first support portion 341 and the first curved portion 351 can be distinguished from each other based on the boundary H.

[0081] An upper flange 310 may be disposed on the first support portion 341, such that the side portion of the upper flange 310 is positioned on the boundary H between the first support portion 341 and the first curved portion 351. Specifically, when the upper flange 310 contacts the first support surface 341a, the side edge 310f of the upper flange 310 is located at a position corresponding to the upper portion of the first curved portion 351 and also corresponding to the boundary H between the first support surface 341a and the first curved surface 351a. The side edge 310f of the upper flange 310 may correspond to the edge formed by the side surface 310g and the lower surface 310c of the upper flange 310.

[0082] Since the side surface 310g of the upper flange 310 extends from the side edge 310f of the upper flange 310 in a direction perpendicular to the first support surface 341a, the side surface 310g of the upper flange 310 can be located on the boundary H between the first support surface 341a and the first curved surface 351a.

[0083] However, this disclosure is not limited thereto. Figure 6 Show along Figure 3 The view taken by line B-B' shows the first support flange and the upper flange according to the second embodiment.

[0084] refer to Figure 6 The upper flange 310 can be disposed on the first support portion 341, such that its side portion is located in the space above the first curved portion 351. Specifically, when the upper flange 310 contacts the first support surface 341a, the side edge 310f of the upper flange 310 can be located in the space above the first curved portion 351, between the boundary H between the first support surface 341a and the first curved surface 351a, and the outer surface 320a of the side flange 320. Since the side surface 310g of the upper flange 310 extends from the side edge 310f of the upper flange 310 in a direction perpendicular to the first support surface 341a, the side surface 310g of the upper flange 310 can be located in the space above the first curved portion 351, between the boundary H between the first support surface 341a and the first curved surface 351a, and the outer surface 320a of the side flange 320.

[0085] Since the side edge 310f of the upper flange 310 is connected to the first curved surface 351a while abutting it, the side edge 310f of the upper flange 310 can be prevented from being exposed to the outside, or the extent to which the side edge 310f protrudes beyond the first support portion 341 or is exposed to the outside in the lateral direction can be minimized, thereby preventing damage caused by the sharp edge of the upper flange 310. Furthermore, since no separate welding operation or connecting member is required to trim the edge of the door 100 formed when the upper flange 310 abuts the side flange 320, the aesthetics can be improved and the manufacturing process can be simplified.

[0086] On the other hand, the side flange 320 may include a cut-off portion 321 formed on the upper end of the side flange 320 to create the first curved portion 351, and may include a flat panel portion 322 separated from the first curved portion 351 by the cut-off portion 321. The cut-off portion 321 may be formed to bend the metal plate to create the first curved portion 351.

[0087] Figure 9 The embodiments according to this disclosure are shown. Figure 3 An enlarged view of the flat panel portion and upper flange of the housing shown. (Reference) Figure 9 A portion of the upper flange 310 may cover a portion of the upper surface 322a of the flat panel portion 322. Specifically, the distance l between the side edge 310f of the upper flange 310 and the plane P including the outer surface 320a of the side flange 320 may be less than the thickness t of the flat panel portion 322, wherein the thickness t of the flat panel portion 322 is the same as the thickness t of the side flange 320.

[0088] Since the thickness t of the flat panel portion 322 corresponds to the outer surface 320a and the inner surface 320b of the side flange 320 (see...) Figure 5 The distance between the plane P of the outer surface 320a of the side flange 320 and the side edge 310f of the upper flange 310 is less than the thickness t of the flat panel portion 322. Therefore, when the distance l between the plane P of the outer surface 320a of the side flange 320 and the side edge 310f of the upper flange 310 is less than the thickness t of the flat panel portion 322, the side edge 310f of the upper flange 310 can be located on the upper surface 322a of the flat panel portion 322, and the lower surface 310c of the upper flange 310 can cover a portion of the upper surface 322a of the flat panel portion 322. In this case, the side edge 310f of the upper flange 310 can be located at the boundary H between the first support surface 341a and the first curved surface 351a, or it can be located between the boundary H between the first support surface 341a and the first curved surface 351a and the outer surface 320a of the side flange 320.

[0089] In this way, the sheared upper surface 322a of the flat panel portion 322 is configured to be covered by the upper flange 310, so the risk of injury due to the sheared surface of the flat panel portion 322 can be reduced.

[0090] However, this disclosure is not limited thereto, and Figure 1 The upper flange 310 of the household appliance shown may not cover the upper surface 322a of the flat panel portion 322. Accordingly, the upper surface 322a of the flat panel portion 322 may be fully exposed.

[0091] The housing 200 may include a second support flange 332, which is formed by bending at the upper end of a first rear flange 361. The second support flange 332 may include a pair of second support flanges 332 formed by bending at the upper ends of a pair of first rear flanges 361, which are formed by bending from a pair of side flanges 320.

[0092] The second support flange 332 may contact the upper flange 310 and support the upper flange 310. The second support flange 332 may include a second support portion 342 configured to contact the upper flange 310 and a second curved portion 352 configured to connect the second support portion 342 to the first rear flange 361.

[0093] The second support portion 342 may have a flat panel shape parallel to the upper flange 310. The second support portion 342 may include a second support surface 342a that can contact the lower surface 310c of the upper flange 310. Specifically, the second support surface 342a may have a planar shape and correspond to the upper surface of the second support portion 342.

[0094] The second curved portion 352 may have the shape of a curved plate having one end connected to the first rear flange 361 and another end connected to the second support portion 342. The second curved portion 352 may include a second curved surface 352a having a curved shape. The second curved surface 352a may have a constant or varying curvature. The second curved surface 352a may correspond to the outer surface of the second curved portion 352 and may be connected to the second support surface 342a.

[0095] When the second curved surface 352a and the second support surface 342a are connected to each other, a boundary V can be formed, and the second support portion 342 and the second curved portion 352 can be distinguished from each other based on the boundary V.

[0096] An upper flange 310 may be disposed on the second support portion 342 such that the rear end portion of the upper flange 310 is located on the boundary V between the second support portion 342 and the second curved portion 352. Specifically, when the upper flange 310 contacts the second support surface 342a, the rear end edge 310b of the upper flange 310 is located at a position corresponding to the upper portion of the second curved portion 352 and also corresponding to the boundary V between the second support surface 342a and the second curved surface 352a. Since the rear surface 310a of the upper flange 310 extends from the rear end edge 310b of the upper flange 310 in a direction perpendicular to the second support surface 342a, the rear surface 310a of the upper flange 310 can be located on the boundary V between the second support surface 342a and the second curved surface 352a.

[0097] However, this disclosure is not limited thereto. Figure 8 Show along Figure 3 The view taken along line C-C' shows the second support flange and the upper flange according to a second embodiment of the present disclosure. (See reference...) Figure 8 The upper flange 310 can be disposed on the second support portion 342, such that the rear end portion is located in the space above the second curved portion 352.

[0098] Specifically, when the upper flange 310 contacts the second support surface 342a, the rear end edge 310b of the upper flange 310 can be located in the space between the boundary V between the second support surface 342a and the second curved surface 352a and the outer surface 361a of the first rear flange 361, above the second curved portion 352. Since the rear surface 310a of the upper flange 310 extends from the rear end edge 310b of the upper flange 310 in a direction perpendicular to the second support surface 342a, the rear surface 310a of the upper flange 310 can be located in the space between the boundary V between the second support surface 342a and the second curved surface 352a and the outer surface 361a of the first rear flange 361, above the second curved portion 352.

[0099] Similar to the first support flange 331, the distance between the rear end edge 310b of the upper flange 310 and the plane Q including the outer surface 361a of the first rear flange 361 can be less than or equal to the thickness t of the first rear flange 361. Since the housing 200 is formed from a single metal plate, the thickness t of the first rear flange 361 can be the same as the thickness t of the side flange 320.

[0100] Since the rear end edge 310b of the upper flange 310 is connected to the second curved surface 352a while abutting it, the rear end edge 310b of the upper flange 310 can be prevented from being exposed to the outside, or the extent to which the rear end edge 310b protrudes beyond the second support portion 342 or is exposed to the outside in the lateral direction can be minimized, thereby preventing damage caused by the sharp edge of the upper flange 310. Furthermore, since no separate welding operation or connecting member is required to trim the edge of the door 100 formed when the upper flange 310 abuts the first rear flange 361, the aesthetics can be improved and the manufacturing process can be simplified.

[0101] When the housing 200 includes a first support flange 331 and a second support flange 332, it can be seen that the support flange 330 is disposed at the rear corner of the housing 200. Specifically, the support flange 330 is described as being disposed in the upper part of the corner formed between the side flange 320 and the first rear flange 361.

[0102] In this configuration, the housing 200 may include a third support flange 333. The third support flange 333 may be formed at the corner where the first rear flange 361 bends from the side flange 320, and the third support flange 333 may connect the first support flange 331 to the second support flange 332. Similar to the second support flange 332, the third support flange 333 may include a third support portion 343, a third curved portion 353, a third support surface 343a, and a third curved surface 353a.

[0103] The first support flange 331, the second support flange 332, and the third support flange 333 may be integrally formed with each other. The support flange 330 may include the first support flange 331, the second support flange 332, and the third support flange 333. The support flange 330 may include a support portion 340, which includes the first support portion 341, the second support portion 342, and the third support portion 343. The support flange 330 may include a bent portion 350, which includes the first bent portion 351, the second bent portion 352, and the third bent portion 353. The support portion 340 may include a support surface 340a, which includes the first support surface 341a, the second support surface 342a, and the third support surface 343a. The bent portion 350 may include a curved surface 350a, which includes the first curved surface 351a, the second curved surface 352a, and the third curved surface 353a.

[0104] However, this disclosure is not limited thereto. Figure 10 A partial cross-sectional view of the housing 400 of the door of a household appliance according to another embodiment of the present disclosure is shown.

[0105] refer to Figure 10The second support flange 332 and the third support flange 333 can be omitted from the housing 400. In this case, since the support flange 330 is not located on the upper end of the first rear flange 361, it is not necessary to bend the metal plate. Therefore, compared to when the support flange is located on the upper end of the first rear flange 361, the first rear flange 361 has a shorter length in the direction perpendicular to the side flange 320. Accordingly, the amount and size of the sheet metal used to manufacture the housing 400 can be reduced, and the housing 400 for the door can be configured to a compact size.

[0106] The first rear flange 361 may include a first fastening hole 361b, and the second rear flange 362 may include a second fastening hole 362a corresponding to the first fastening hole 361b.

[0107] Specifically, the first rear flange 361 may include a recessed portion 363, which is formed as a recess on the outer surface 361a of the rear surface of the forming gate 100 of the first rear flange 361 in a direction toward the front panel 210. A first fastening hole 361b may be formed as a surface 363a passing through the recessed portion 363, which forms the recessed portion 363 and extends parallel to the front panel 210. A second fastening hole 362a may be formed as a second rear flange 362 passing through at a position corresponding to the first fastening hole 361b.

[0108] A portion of the second rear flange 362 can be inserted into and positioned in the recess 363. The portion of the second rear flange 362 inserted into the recess 363 is the portion in which the second fastening hole 362a is formed, such that when this portion of the second rear flange 362 is inserted into the recess 363 of the first rear flange 361, the first fastening hole 361b and the second fastening hole 362a can overlap each other. The first rear flange 361 can be connected to the second rear flange 362 by means of conventional rivets, pins, or screws passing through the first fastening holes 361b and the second fastening holes 362a.

[0109] In this way, the second rear flange can be fixed to the first rear flange using conventional fastening components such as rivets, pins, and screws, without the need for separate welding operations or special fastening components, and the number of fastening components can be minimized, thus facilitating the manufacture of housings and doors.

[0110] Although several embodiments of the present disclosure have been shown and described, the above embodiments are for illustrative purposes only, and those skilled in the art will understand that changes and modifications can be made to these embodiments without departing from the principles and scope of the present disclosure, the scope of which is defined in the claims and their equivalents.

[0111] Although this disclosure has been described with reference to various embodiments, various changes and modifications may be inspired in those skilled in the art. This disclosure is intended to include such changes and modifications that fall within the scope of the appended claims.
